mRRovRMRNT 1N rAeeotrJs FOR RAILROAD RAILS.

TO .ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL L; POTTER, of Wyandotte, inthe county ot: Wayne, and State of Michigan,

have invented a new and improved Rail Pile; and I do hereby declare that Ithe following is a full, clear, and exact description thereof, which will 'enable those skilled in the art to make. and -use the sameLreference being had to the accompanying drawings, forming part of this specicatiomin which- Figure 1 represents a transverse section of my improved pile or faggot, one -half the actuall size.

Figure 2 is a transverse section of the same,` illustrating a manner of applying old` railroad bars in place of the inner or intermediate iron bars -of the pile.-

Figure 3 represents a transverse section of the complete rail, full size.

Similar letters of reference indicate corresponding parts. l

This invention consists in forming a pile, from which railroad rails vare drawn r rolled, of bars of iron and steel, arranged or disposed substantially as hereinafter described, and in such a manner that the rail will be rolled with asteel head, the latter protected from Aundue heating, and. the iron and steel perfectly welded together by the rolling operation. l p

In fig. 1 aa represent twobars of iron, seven inches broad and one and a quarter inch in thickness, and b represents four bars of iron, three and a half inches in breadth and one -and `aquarter inch in thickness.- These bars, a and'b, are placed edgewise, side by side, the narrow bars, l, leaving a recess pito receive a bar, c, of steel, live inches in width and three and a. half inches in thickness. This steel may be manufactured by the Bessemer or pneumatic process. This pile, thus formed, is rolled cdgewise, and a rail produced, as shown in iig. 3, A being the steel head; and B the iron neckand base. In tig. 2i's shown a pile of the same construc-v tion and arrangement, the interior or intermediate iron bars, 5 consisting of old railroad rails. By these'means'it will be seen that the steel will be brought to ajvelding heat, and fully protected by the iron, as the steel will weld at a much 4lower heat than the iron, and the two metals will, during the process of rolling, be perfectly welded together.

Having' thus described my invention, whatpIclaim as new therein, and desire to secure by Letters Patent, is-

A `pile or 'aggot4 for rolling railroad bars, constituted of iron and steel bars, arranged substantially as herein represented and described. y
